Th s invention relates to an improved car tank discharge means, and more particularly,

comprehends a discharge valve and a valve stem adapted toreceive heat from a heat discharge outlet,

It is an obgect or the present invention to provide a valve, a valve stem or rod and a valve OPEEStlZHIQmQBHS for a car tank or the like, which parts are heated whereby to main- ,tainthe ladinlg of the tank ear in such 1 3 opening fluidity the same may be readily dis- I charged through the outlet.

Another object of the invention is to provide a novel construction of discharge valve and valve operating means fer tanks or the like I I V Referring now more particularl to the drawings, A indicates a car tank aving a bottom 1 and a top 2, the latter being provided with a dome 3. The bottom is provided "with a discharge outlet comprising a jacketed. casting 4: having an inlet pipe 5 and an eutlet piece and a central discharge e casting is interiorly threaded adjacent the tank end as shown at dared has mounted therein an externally 'threadedannula'r ring?) which screws into tank .end of casting and is formed with a valve seat upon which the lower end of a valve B is adapted to seat.

- ring 9 is provided with vanes 10' which extend'upwardly therefrom and are preferably formed integral with a tubular carrier element 11 in the formof a sleeve, the latter having an external thread 12. The construction just described forms a valve guide and carrier as will be hereafter described.

The valve B comprises a sleeve 13 having its lower edge 14 formed to engage the valve seat 10, and its upper end isreduced as shown at 15 and internally threaded to engage the lower end of a tubular valve rod 16. Looking means such as shown at 17 are provided, the same having screws 18 engaged in grooves defined by adjacent ribs 19 serve as limiting stops for an actuator 27 in the form of a sleeve nut the same being internally threaded to engage and work on the threads 12 of the carrier element or sleeve 11, said nut bein provided with spaced lugs 28 adjacent the ower edge thereof.

The shoulders 26 are provided with recesses which recesses aline to form substantially a circumferential groove for supporting a spring ring 29 which, as clearly shown in Fig. 1, supports a vertically arranged -plate 30 positioned between adjacent shoulders 26 and serving as an abutment or pperating member as hereafter described. eferring to Fig. 1, it can be seen that the abutment 30 extends upwardly beyond the horizontal plane of the shoulders 25, and the valve B has its casing so formed, as shown at 31, as to provide a recess in the side there of to accommodate the upper end of said abutment 30 and to prevent lateral move-. ment' thereof with respect to the valve.

With a valve construction as described,

the operating mechanism therefor is located within the sleeve or shell 13 and hence shielded from direct contact with the tank lading.

' with the shoulder to be raised from its seat by said lugs, theredischarge outlet to permit Assuming the parts to be in the position illustrated in Fig. 1, that is, with the edge 14 of the valve B in enga ement with its seat 10, it is sewn that the ug 28 is seated on the shoulder 26. To open the valve, the hand wheel 22 is rotated thus turning the sleeve 13 and the abutment 80, the latter contactin with one of the lugs 28, thereby turning t e sleeve nut 27 on the carrier 1l and elevating said nut. Continued rotation of the valve will bring the lugs 28 into contact with the'upper shoulder 25,.and during the rotation of the sleeve nut27 on the carrier 11, and up to the time of the engagement of the lugs 28 with the shoulder 25, the valve B still remains on the seat 10 rotating thereon and during such rotation. it will be apparent that the edge of'the valve B is ground to its seat 10. The continued rotation of the sleeve 27 as before mentioned will bring the lugs 28 into contact 25 and cause the valve by opening the the dischargeof the contents of the tank. I reversal of rotation of the valve rod 16 will cause the nut 27 to be lowered, thus engaging the lower shoulder 26 and forcing the valve Bto seating position, valve B reaches seating position, rotation thereof will also serve to grmd the edge of the valve on the seat 10 and also lower the sleeve 27 until it reaches the position shown in Fig. l with the lugs 28 in contact with the lower shoulder 26 at which time the valve B is positively retained on its seat 10 by the engagement of the lugs 28 with the shoulder 26, as will be obvious.

It is to be noted that with the construction just described, there is provided a continuous opening through the valve, valve rod and cap 2s to the dome. As before-mentioned, the discharge outlet is jacketed permitting a heating medium, such as steam, to be passed from the inlet 5 through the jacket and out through the outlet 6, thereby heating said casting or discharge outlet, and because of such heating, the air in the discharge outlet passage 7 will be heated and will be'passed upwardly, past the vanes 10 and through the hollow carrier 11 into the valve B and then upwardly through the valve rod 16 and into and out of cap 24, this passage of heat serving to heatthe contents of the tank adjacent the valve and its rod, thus aiding in maintaining the fluidity of such contents.

The casting 4 is provided with tapped openings which are, in the instance shown, closed by plugs 31. These openings are provided for the purpose of permitting the attachment of heating coils for the interior of the tank to the casting whereby to circulate a heating medium throughoutthc contents in the tank.
